Using rsync to migrate to a new webserver.

[Scott Sherman]

Hi.  I am a Systems Administrator for a web design agency in London.  We have recently purchased a new webserver (web5) and would like to migrate over to it from an older machine (web4).  Both machines are running RedHat 6.2.  If possible we would like to perform this migration without any downtime.   Basically there is a directory called /web which I wish to copy from web4 to web5.  To do this, I have entered the following (from / on web5):   rsync -avz -e ssh --progress (web4's ip address):/web ./   It copies all of the files over.  However, after completion, the destination '/web' directory on web5 is about 100 MB larger than the source '/web' directory on web4.    Does anyone know the reason for this increase in size?   Also, is this a sensible way to do things? I am concerned about the fate of files that are being altered while rsync is being run.   Thanks,   Scott Sherman
